blueprint

[ancient siren]

new is hit actor, and old is interactable hit actor

idk if you needed to know that

when i throw the gun and it is more than 200 away from me i get this error

[odd ember]

you know there's an extra cost associated with every reroute node?

[ancient siren]

wdym

[odd ember]

it costs memory to use it

[ancient siren]

oh

[odd ember]

it's not just free

[ancient siren]

good thing i removed them

[gentle urchin]

Its worth it

for sanity

[ancient siren]

agreed

[odd ember]

generally I try to make setups that don't require reroutes

[ancient siren]

a little cleaner

[gentle urchin]

otherwise the spaghetti monster will just continue to grow, and eat up from my screenspace

[odd ember]

it's a good sanity check in and of itself: if you need reroute nodes you can probably rewrite your logic

in a more sane way

[ancient siren]

😰

[ancient siren]

what you are saying is not the issue rn

[gentle urchin]

this logic seem flawed

by appearance

[odd ember]

I was more referring to this comment

[odd ember]

I mean this still isn't particularly readable

[ancient siren]

well ik but it works for me

[gentle urchin]

Sequence, branch, double do once,

another sequence with two branches

this part

[odd ember]

cool, but if you want someone to help you then maybe that's a reason to clean it up

[gentle urchin]

these two are mutually exclusive

[gentle urchin]

so there's no need to check them both

[ancient siren]

the issue is when i get close enough to it it is not getting the outline

[gentle urchin]

well, perfect 200.0 would not be exclusive, but i bet that's not by intent

[ancient siren]

wh

[gentle urchin]

exactly that part

either its > 200

or its not

[ancient siren]

what are you on about-

[onyx token]

i'm confused for why this cast fails

[ancient siren]

if i do that it is inverted for some reason

[onyx token]

i'm trying to get the parent actor of my player character...

[ancient siren]

it doesnt work

so

[onyx token]

my player character is a child of my parent actor...

so it should work shouldn't it?

[gentle urchin]

Also your do Once doesnt have resets to them , which may also cause trouble

[ancient siren]

how would i add a reset to this?

[gentle urchin]

well a reset to "stop tracing" would normally be "start tracing"

[grand valve]

No. Parent actor is just the actor you are attached to or who owns. Its nothing to do with class hierarchy here

[gentle urchin]

If there was need for such a doOnce, that is

[odd ember]

that's not how inheritance works

[onyx token]

no?

[ancient siren]

there is

[onyx token]

hm

[ancient siren]

idk why

but it needs it

[grand valve]

@onyx token you should remove the parent actor node there and it will work

[gentle urchin]

This is tick driven, right?

[grand valve]

*should

[ancient siren]

me?

[onyx token]

but my variables are part of the parent blueprint tho

not part of the child

[ancient siren]

because yes it is

[grand valve]

child has access to all parent variables

[onyx token]

oh

wait hang on

[gentle urchin]

Its also hard to say whats really going on. Whats "activating" the outline?

[onyx token]

but what do i cast to then?

[gentle urchin]

"Start tracing" ?

[grand valve]

@onyx token probably just your character parent

[grand valve]

a child of a character_parent BP will return true when you cast to the parent

[onyx token]

hm still fails...

oh wait

i'm dumb

i didn't set this in the parent blueprint

[grand valve]

🙂

[gentle urchin]

Right , ok

so I'd clean this up a bit really

I'd probably also use an interface for the highlight

[ancient siren]

it is going up and down so you can see it all

otherwise id have to send two screenshots

[onyx token]

thank you for the help!

[gentle urchin]

yepp, it's not really what i ment by "clean it up "

[ancient siren]

oh

right

okay

[gentle urchin]

I dont care much about how you handle your visuals 😛

but there's a lot of stuff here that doesnt need to be here

[ancient siren]

...okay

[gentle urchin]

from the original screenshot, whats to the left of there?

[gentle urchin]

aaand before that?

what event drives this?

[ancient siren]

tick event

[gentle urchin]

ok

is this within the controller ?

[ancient siren]

yep

this is the event graph of the BP_Player

[gentle urchin]

gimme a sec

gotta set this up

with the outline material

[ancient siren]

you want me to send it to you?

[gentle urchin]

Nah

i got one

[ancient siren]

oh ok

should i get some chips while you are "setting up"?

[gentle urchin]

xD

[ancient siren]

like

is it enough time

[gentle urchin]

yes

[ancient siren]

kk

[odd ember]

oh my days it keeps going

just real quick, what is it that you want to do that requires this much code in one place?

[ancient siren]

outlines

for a gun

[faint pasture]

@ancient sirenVariables my man

[ancient siren]

never heard

[faint pasture]

You've never heard of a variable?

[ancient siren]

omg

[odd ember]

when you say outlines you mean like trails?

[ancient siren]

im kidding

[ancient siren]

nope, just an outline

[odd ember]

of a character you mean?

[ancient siren]

ill send a vid

[faint pasture]

That's an unreadable clusterfuck. Reorganize it in such a way that only execution is traveling all over the place and it'll be a lot cleaner

[odd ember]

because if it's anything to do with just visuals

I promise you setting up a postprocessing material is less work

[ancient siren]

when you are in range of it (and you can pick it up) then it has an outline

if not you dont have an outline

and the issue is that when i throw it and it is out of that range and the outline goes away

it doesnt come back

[onyx token]

dang inheritence
So how would i solve this? Only my player character - the child of the character parent - has a "follow camera" component, the Character parent doesn't.

[faint pasture]

Why does it go away? What is driving whether outline is shown or not?

[odd ember]

okay that's really simple. on the weapon on the ground, make a collision sphere that is the size of the radius you want it to be. then when you enter it, set Use Custom Depth to true

when you leave, set it to false

[ancient siren]

i just followed a tutorial man idk

im new

[odd ember]

once you have that, all you need is the postprocessing material

[faint pasture]

Yeah that's the core of your problem. Learn to paint, not just paint by numbers.

[odd ember]

which is like a 5 min job

[ancient siren]

i already have a material and everything

[odd ember]

okay

so do what I just said

that's 2 mins

no need for complicated stuff

[gentle urchin]

sphere, and check for distance

[odd ember]

I mean why

[faint pasture]

Show where in your code the outline is shown/hidden

[odd ember]

just use collisions on the weapon

[gentle urchin]

distance was by intent

to not highlight objects far away

[odd ember]

yeah so highlight them when you enter a collision

[gentle urchin]

that could highlight several

[odd ember]

the collision is on the weapon and has a radius

[gentle urchin]

its a focus thing

[odd ember]

then make an additional check to see if it's where the place is facing

it's really not more complicated than that

[faint pasture]

Then you have 2 glowing weapons etc. This is a 2 part problem.
Part 1
Have a variable on item representing whether or not it's focussed/highlighted
Part 2
Have that variable drive the material.

He already has Part 2, just doesn't have Part 1 set up correctly

[ancient siren]

can i temporarily disable code like doing this in normal languages?

// if (wtv)

[odd ember]

you can

but you can also just unhook the execution

which is faster

[ancient siren]

how?

[odd ember]

alt click the execution thread

[faint pasture]

Just unplug the white pin

[ancient siren]

oh.

i thought it woiuld be more complex than that but ok

[odd ember]

the best things in code are simple

[onyx token]

nothing is ever simple

[ancient siren]

agreed

[faint pasture]

@ancient sirenHonestly though, stop where you're at, and do SOMETHING on your own. You're way over your head just following along to a video.

[ancient siren]

i learned gml this way and it seems to be working in ue4

[faint pasture]

OK so, start with this. Figure out where in the code the outline hiding/showing happens.

[gentle urchin]

something like this should work

[ancient siren]

well ik where it is

[odd ember]

hows the anim state machine going?

[onyx token]

it's goin, right now i'm trying to simplify my character so i don't cast a bunch of times

the idea is to have a parent character class, and make a bunch of player characters / npcs / whatever as children

[gentle urchin]

and just let the highlightable item react to the hit

[peak summit]

How do you change a specific material in the Materials section at runtime by the Element? This horse for example has 4 mats, one for eye, hair, main body. Want to swap "Element 1"

[gentle urchin]

set material ?

[odd ember]

good thinking

[barren sonnet]

Im trying to use splines to draw into the terrain virtual texture for roads and such . Does anyone know what actions I need to add to draw into it ?

[onyx token]

well now i'm struggling with inheritence
This doesn't work. I'm trying to access something in my animation blueprint that only one of my child classes can have

[peak summit]

well that's embarrassing

[odd ember]

what is your full hierarchy?

[gentle urchin]

quickly change your username before someone sees it! /jk

[peak summit]

my excuse is im coming from unity pretty fresh and everything is pulling teeth and i simply... assumed it was very difficult =/

[gentle urchin]

experienced major issues with virtual texturing, but you may have better fortune . Otherwise Render Target is an alternative ^^

[odd ember]

that's not your hierarchy

[gentle urchin]

No worries, we've all been there

[odd ember]

your class hierarchy

[onyx token]

oh, it's parent character => player character

And the idea is that the animation blueprint is specific to the parent character and can be used by all children

But now my player character has a camera and no npc does

and the camera manipulates some bones

does that mean i should make 2 different animation blueprints?

[faint pasture]

Multiple skeletal meshes can use the same skeleton and animbp

[gentle urchin]

If you by chance choose to go by the render target route, all there is to do is walk along the spline and draw at location

[odd ember]

okay don't do that

[onyx token]

b...but

[faint pasture]

@onyx tokenWhat's your goal, what are you trying to do?

Have a concept of LookDirection and modify animation for that?

[onyx token]

Yeah

[faint pasture]

ok then put a rotation or vector on your character and drive it

[onyx token]

how do you mean?

it needs to use these

and i've made it so it can go 180° without looking weird

[barren sonnet]

Thanks Squize I'll try that. My plan was to use a mesh instance and apply a texture / renter to virtual texture to each instance so it would raw into the terrain..

[odd ember]

you shouldn't ever do on the animBP something for just one class. the whole idea is taht it is generic

otherwise you need an animBP subclass

[onyx token]

hmm

i guess my NPCs are gonna have a lookat function too

[gentle urchin]

Sounds like it would work better than what i tried to do tbh! there were clear issues with overlapping and segmentation during my attempt with virtual texturing, but the tutorial may have been.,.. questionable aswell 😛

[odd ember]

yeah I do lookAt for all my characters

[earnest stream]

hey guys, with event bindings, is it 'safe'/not-inefficient to do this? ('null' is an empty function since its a by-ref input that cant be left empty)

[onyx token]

Maybe the player lookat is kinda special tho...

i'm not sure

[ancient siren]

whats the node to check collisions?

if there is one, of course

[odd ember]

OnComponentBeginOverlap

and

OnComponentEndOverlap

[ancient siren]

kk ty

just like c++... of course

[barren sonnet]

@gentle urchin Got it working and it seems to run fairly well. I just had to make the Virtual texture variable visible when placing the spline so it could be selected. Thanks for your help!

[odd ember]

you can add a bCanLookAt in your parent character and set it to false

[onyx token]

ok how about this then:
Fuck the calculating head rotation in anim blueprint-
I'll just get the rotation from my character blueprint, and i do all the calculating in there

that way the child class can do whatever it wants

[ancient siren]

this doesnt look right

the gun is Interactable btw

[odd ember]

no OnComponentBeginOverlap is an event

it'll be a red node

[ancient siren]

that makes way more sense

[odd ember]

you'll need to select the collision component

then it'll appear at the top of the right click menu

[ancient siren]

wdym

[odd ember]

in the hierarchy

[ancient siren]

ohh

i see it

yeah

[quartz mural]

How can I get the "furthest left" vertices from an array loop on a procedural mesh?

[odd ember]

depth first search?

[quartz mural]

ok, I'll look that up.

[odd ember]

I don't think you can in BP

[quartz mural]

oh, pain

I just need to check this array for the nodes that are furthest left. So I suspect I can just compare each index's value to the "max" value of any index.

So first I need to know how to get the max value out of the index, and then I can just run the compare to pick the ones I want.

[odd ember]

but can you reliably know that for any rotation?

[quartz mural]

Rotation doesn't matter, left was just a word I used to draw the point out.

[odd ember]

okay but still

[ancient siren]

help?

[quartz mural]

I'm going to send the line checks outward from the floor, then consider where walls belong.

[odd ember]

the location of that point will change

[odd ember]

show the code where you set custom render depth

[odd ember]

okay so

the outline, I don't know what you have made

but if it's a postprocess material you'll need to do on the player

[ancient siren]

this is the players bp

[odd ember]

okay, so you need to set custom render depth on the gun

[ancient siren]

idk how to do that

[ancient siren]

but isnt that just this

oh shoot

i just

i just did this and it showeds

[odd ember]

yep

[ancient siren]

showed

[odd ember]

but

on the cast

you have the gun

as a variable

so just set it through that

and then when you leave just remove it again

that's literally all you need to do

no complex distance checks etc.

you don't need to reinvent collision

[ancient siren]

I AM SO SORRY

for bugging you

but

[ancient siren]

set what??

[odd ember]

BP-gun

sorry the mesh component on BP-Gun

remove the get component by tag

you dont need any of that

just the cast node itself

and from the cast node, get mesh

[ancient siren]

sorry

[odd ember]

well that's the same image lol

[ancient siren]

i just removed something dumb

[odd ember]

idk if discord is f'ing with people today

[ancient siren]

no its me

its a different image, trust me

[ancient siren]

ok

i cant make it the mesh

[odd ember]

you need your gun mesh

whatever it's called

[ancient siren]

FP_Gun

[odd ember]

the gun mesh on the gun itself

show the gun hierarchy

[odd ember]

ok yeah

so that

[ancient siren]

when i drag off of the As BP Gun and type FP_Gun nothing shows up

[odd ember]

try and type in "skeletal" and see if it finds anything

[ancient siren]

it said Get Skeletal Mesh

so i pressed enter

and it popped up outside of the As BP Gun

[odd ember]

hmm why is it not connected

do you not have context search on?

[ancient siren]

nope

OH

I GOT IT

fucking FINALLY

THIS SHOULDNT HAVE TAKEN ME THREE HOURS

tysm

i really appreciate it

[odd ember]

no worries. there's still some kinks you can iron out

but that's the major part of it

[ancient siren]

it works for now

@odd ember

i promise this will be quick

but

[odd ember]

some kinks

[ancient siren]

it is when i collide with the gun, not the collision circle

[ancient siren]

precisely

[ancient siren]

^

that is an issue because it only has the outline when i am directly on it

not on the collision circle\

[odd ember]

just select the collision you want to use

and create a new event

[ancient siren]

so i want to use the on component end overlap (collision circle)

so id make a custom event with that?

[odd ember]

the same way you made it with your capsule

just do it with whatever other collision you wanna use

[ancient siren]

the issue is that the collision circle is in the gun BP

and i cant get it in the player bp

should i make the collision circle be in the player instead of the gun?

[odd ember]

if you make it in the gun, just cast to player to check for the player

but yeah you can make the same setup

[ancient siren]

i made it in the player and it works much better

ty

[languid spear]

a common suggestion to improve performance is disabling tick on actors. But I often worry about unexpected consequences of this. If no code is being run using event tick inside the blueprint, then tick can be disabled, simple as that? Or could this impact other things, perhaps net updates for example?

very good to know. thank you!

[odd ember]

just don't disable tick on player controller. that is all

wait that's a thing?

[faint pasture]

You monster...

I have some pretty fancy BPs so can I use Papyrus?

Everyone knows Papyrus is fancy

[trim matrix]

How does this not return the object?

[faint pasture]

Return what object?

[trim matrix]

Oh do i need to add

like a int to the forward vector

[trim matrix]

bascially im trying to recreate a ray tracer

*not ray tracing

does it matter how large it is?

so like 200?

[faint pasture]

Assuming the player controller 0's position and rotation are what you actually want to use, then you want to trace from its location to its location + Forward x SomeBigNumber

[trim matrix]

oh wow

[trim matrix]

ah thanks

thanks to you to Lorash

[odd ember]

looks like some UE5 nonsense. but also I love the comic sans

this is the first I hear of it, but yeah I always wanted this

so it's like an early holiday present

I have just done this for my project

I consider that my work on my project for the week dusts hands

thanks

[faint pasture]

That's the worst productivity killer.
"welp, I commited something, time to fire up Elden Ring"

[odd ember]

yeah if only I would actually play games then I could at least rationalize that as "research". instead I'm on discord doing nothing 😂

[peak summit]

Man I cannot find any way to hook into the points or sections of terrain splines to toss to pathfinding. How we contact the devs 😅

[icy dragon]

That's a good idea for a tool.
Though I can only do Dear Imgui lol

[peak summit]

Speaking of fonts.. can you overwrite roboto with your own asset so it updates everything using it?

Prototype with default but obviously will want to replace it later

I can overwrite it?

Gg

Works for me 😆

[peak summit]

Sometimes I wish I never learned unity. I'd have less concerns 😆

[icy dragon]

https://forums.unrealengine.com/t/changing-the-editor-font-to-any-other-font/230877

[peak summit]

Oh I don't care about the editor font just what's in all my widgets

[icy dragon]

If I'm not mistaken the editor font asset uses the same font files as those

I'll check it once I'm done dealing with C++ stuff

[peak summit]

Hmm ya it does so if I replace it would it change the editor lol

I might want to make a new ttf for my widgets called game font that I can replace before I get too deep in UI

[icy dragon]

That's way better and more preferred. Normally you shouldn't mess with editor .uassets

[peak summit]

Sure hope someone can ever answer my terrain spline question on how to get the points via API or hook into it during editor to at least create a run time accessible data set to use with pathfinding

Really critical to the game idea

If they only made it for editor time and you can't hook into it to duplicate a spline that'll be a huge blow

[icy dragon]

I haven't used terrain splines in a while, but weren't they bunch of actors?

[peak summit]

It's not anything that shows up in the hierarchy

I just really like how it conforms the terrain and can put down a texture without actually deforming the terrain

If you delete the layer it simply restores the terrain

[oak cape]

Unreal marks a BP as dirty when a Breakpoint is enabled on a node. Is there a setting to turn this behavior off? It's quite annoying to have multiple Blueprints that are marked dirty which are then saved (it's easy to forget which BP actually has changes and which one is marked dirty only because of breakpoints) and pollute a commit with BP changes that really have no real changes.

[trim pollen]

is there a better way to do this? is this way dumb? goal is to increment a value while X is held, decrement while C is held

[hardy fable]

its not dumb if it works. using the flip flops is a little obfuscatory in as much as crossing streams of code is generally a bad idea. it works here since flip flops use local variables internally (and thus isnt actually crossing between code paths). i still would be inclined to just have boolean properties set when input is held. Technically, a "cleaner" way you might do it is set your inputs up as axis inputs so that they constantly trigger. then you would not need to use the event tick node at all, as they tick for you.

[trim pollen]

its not dumb if it works.

hooo (idk what i'm doing so 😛 )

and okay yeah that makes sense, thank you

i'm probably going to be setting a couple other variables like this in the same blueprint, which is probably gonna get messy since it's all on event tick :/

oh just saw the last part of what you said

[hardy fable]

yeah, having a bunch of code hooked into tick that conditionally fires like your code above is generally going to get messy eventually, and should be separated out into event driven systems when possible. in your case since your system does do stuff per tick you need something running on tick in order for it to increment/decrement per frame. thats why i suggested the axes input method as that would still be per frame, but not required using the tick node

*ALSO, your current code is going to not run the same on computors running at differant framerate (higher fps pcs will have their fov change faster, since they are ticking more)

to fix that, multiply the addition node result with the delta seconds pin

unless you want high fps computors to have fast fov change, obvs

[trim pollen]

awesome, gonna try switching to input axis now, thanks! and that is good to know

[hardy fable]

as a general rule thumb, you should multiply whatever you on doing on tick by the delta time. that is why they provide the pin

[hardy fable]

if you do use axis inputs, the same problem exists, but axis nodes dont give you a delta pin. in that case you need to use the world delta node instead

[trim pollen]

this way is much better! thanks again

[hardy fable]

np! youll pick up these tricks over time

[faint pasture]

Just have them set Increment to 0 when released

or add/subtract on press/release

[icy dragon]

Do note however that World Delta Seconds is affected by time dilation. If you have slow motion going on in gameplay by reducing global time dilation, it will affect whatever that use World Delta Seconds.

[trim pollen]

I haven't attempt to do anything like that yet, but good to know

[hexed glade]

I've encountered something I don't understand while running macros with built in delay. Part of the macro function is adding and removing from a structure array. If I run it multiple times, it will always do the first part before the delay (which is adding to the array). Then after the delay it will only fire the removal from the array once. Does anyone know why this happens?

[wicked osprey]

Guys, why can't you return ref from an array of Objects?

[icy dragon]

Because it's an array of object reference?

[maiden wadi]

Can just call SetArrayElem if you need.

[fair magnet]

I made a custom event with a pass by reference property but it's showing me a warning that no value will be returned?

why not? :(

[hexed glade]

Found out why the macro isn't working. Apparently when you fire multiple instances of macros with delay, the later instances are canceled while the first macro is waiting to finish its delay. I tried splitting the macro into two with the delay running in between, but it seems it doesn't work either.

[fair magnet]

I wonder how do I create an over time intensifying shake?

[icy dragon]

Timeline node, if you don't want to clutter the Event Tick

[fair magnet]

yea that for sure :o but how do I get the shake itself to update? as far as I can see i only have the option to start a shake with a certain scale

[icy dragon]

I'm certain you can save camera shake object reference 🤔

[fair magnet]

I guess that could work :o

[oak vine]

Hey guys, I've got a small 'understanding' issue with timelines inside a Blueprint actor. I've set up my Blueprint in a way that there's a 'reset' event at the start of sequencer to reset the animation back to its initial state. However, when I've got sequencer in 'playback loop' mode the Blueprint actor animation starts to 'snap' on the second and following rounds of playback (as you can see from the video below).

From what I can see, it's because the timeline hasn't finished playing yet. If I wait a couple of seconds before playing sequencer again, the animations behave as expected.

However, I don't want to wait! 😄 So how can I force the timeline nodes for the Blueprints to be finished and reset to their respective start positions when sequencer loops back to the start?

[abstract socket]

I'm trying to smooth my Character's Capsule from its half-height to crouched half-height but the problem is whenever it does so, there's some sort of offset (perhaps due to the shrinking of the collision capsule?) going on, which means the character's position kind of jitters on the Z axis.
In fact, if I take my character's location before crouching and after crouching, the Z location differs.
I'm simply lerping with a Timeline and then using SetCapsuleHalfHeight to set its new height.
The value lerps correctly between its start and end values, with a difference of 55, but as you can see in the video, by taking into account the starting location of the crouch, the end location is not exactly endZ = startZ - 55, but differs by it by some decimal points and as such the character gets pushed down / up.

[fair magnet]

I mean if you want to have a specific value just set it to that specific value if you need it? :o

[oak vine]

Thanks Ayes, I've done that though using the reset event at the start of sequencer, right?

It's only that the Blueprint doesn't seem to get that information.

[fair magnet]

I'm barely ever using the sequencer So Idk

[viral basalt]

Why cant I connect multiple executions sockets to a blueprint function output?

[fair magnet]

So I wondered if I get a float... is this treated as a reference ? Can I do set-by-ref?

[fair magnet]

drag over the triangle... not the node

also this isn't going to work

return breaks functions

[viral basalt]

hm

so is there even a way to wrap the For Loop node?

I want to input an amount of iterations instead of two indices

[brisk sinew]

Cuz functions are designed that way. Use a macro if you need multiple execution pin outs

[fair magnet]

macro

[viral basalt]

ooh thank you. thats the keyword i was missing. I will look into it

[brisk sinew]

Or if you need multiple returns, just add more funtion returns

[fair magnet]

So still o.o Are get-nodes of floats or vectors actual reference? or just copies?

[brisk sinew]

There are two get nodes from arrays. There is one for both get ref and get copy

Or are you talking about straight variable getters for float var and vec var?

[fair magnet]

not arrays

that's what I wanna do

[brisk sinew]

Never used that node before.

Like

Ever

[fair magnet]

I could obviously just switch but it looks cleaner that way :o and is less copy paste

[brisk sinew]

Whatever works

[fair magnet]

yea that's the thing I don't know if it works xd

[brisk sinew]

Oh so its just like using pointers or & in c to pass a var by ref in a function parameter

Well only way to know if it works is to unit test it

[brisk sinew]

I think the target is supposed to be your function's vector input. And the value the selected location vector

[fair magnet]

The target is whatever variable I wanna set

The value is... it's value

It seems to work but I'm currently tryna figure out what's saving my progress o.o Because I unplugged it but still works

[brisk sinew]

Only reason stuff saves between play sessions is the save and load functions. Or between levels is gamed instance

[fair magnet]

so yea value does in fact change

[viral basalt]

Made it into a macro. Thanks a lot for the help

[brisk sinew]

Huh. A for loop macro for the for loop macro. That's new

[rain egret]

i have a function thats there to offset and rotate a vector array.
basically i have a procedural mesh at the root component that builds a convex collision.
as we know only the root component checks for collision if he moves, thats why i am taking the mesh data of attached parts and add this in form of a convex collision. basically tricking the procedural mesh to add a collision where those parts are. this works.

however and this is the point i need help with, picture two shows the convex collision on the ship that has not rotated
picture three shows how my function handles rotation if the ship actually rotated. the location works, only the rotation doesnt wanna play nice.
any help would be appreciated, i think its literally a few nodes that would fix this but i am no expert at vector math so i am stumped

[rain egret]

inverse transform did it

[fervent raft]

Given a world transform vector, a rotator, and a double, is there an easier way to get the world transform vector in the direction of the rotator at the distance of the double without doing a lot of math and using a lot of nodes?

[maiden wadi]

The world transform in this case is pointless unless you're looking for a world offset of the transform in the direction of the rotator.

[fervent raft]

well i drew a picture

[maiden wadi]

I'm still not sure if you're looking to just rotate the vector. Or multiply the rotator's vector by the double and add it to the world location you have.

Not sure what Known vector on that is, as it's a line.

[fervent raft]

neither i need to find a new vector given a vector, a rotator from the initial vector, and a distance along the direction of that rotator

[stone wind]

guys the hits arnt registering any help

when i shoot it sometimes goes through the A.I.

pls can i have help

[jaunty summit]

https://www.quora.com/If-we-have-two-sides-one-angle-how-we-can-find-another-side-of-a-triangle

[stone wind]

what should i do

[fervent raft]

thanks man but its 3d so its complex

[jaunty summit]

How is that different?

[fervent raft]

i think ive almost got it though

[icy dragon]

Looks like classic pythagoras equation

[fervent raft]

i have to figure out a 2d triangle in 3d space before i can do that

[fervent raft]

i know but in 3d its harder

[jaunty summit]

Given this you would find the magnitude of the unknown vector. To find the angle(direction) you would want to use the dot product of the unknown vector and the known vector/known distance

[jaunty summit]

#gameplay-ai

[maiden wadi]

That's not really an AI issue though. Nothing to do with Behavior trees or AI programming.

[maiden wadi]

You need better information. What is hits? Line traces? Hit events from a moving projectile with collision? What is sometimes?

[jaunty summit]

He actually asked there before I told him to 😄 , but yeah you're right

[fervent raft]

In case anyone was curious, I found an easier way: make a new vector with the size of the known distance, rotate it with the known angle rotator, and add it to the known vector

Avoids a lot of trig

[earnest tangle]

You mean hides the trig inside the rotation node ;)

[fervent raft]

:)

[jaunty summit]

Well yeah it's simple addition/subtraction of vectors. The fact that I didn't see arrows(vector directions) made me think about triangle laws lol

[dire frost]

Did you use the correct trace channel?

[fervent raft]

Yeah I was definitely not explaining it clearly

[stone wind]

uh

[viral basalt]

can/should a function not wrap another function?

[dire frost]

If you're using bps then by default the trace channel for the line trace should be "visible" if that's the case then maybe check the collision channels for your pawn and check if it's blocking against the visible channel or not

[dire frost]

Do you mean like calling a function within a function? If so yeah you totally can

[jaunty summit]

If you don't want to do the -1 each time, there's a foreach node

[stone wind]

look, im knew to ue4

but i have the collision lines shown

but when i hit with a bullet

that applies damage

it doesnt register

even though the A.I. has

a damage reciever

it works sometimes

but most of the tikmes it doesnt

[viral basalt]

is that better? I would still need a list of indices would I not? Doing it like this was convenient for me because I had another node that needed those index and iterations inputs so wrapping the for loop likt that seemed like a good idea

[stone wind]

so

[jaunty summit]

Well you get the Array Index in a ForEach node too

But you need an array for that. I'm not sure what you're iterating though

[viral basalt]

just indices

[jaunty summit]

Ah ok, then this node isn't relevant for you

[viral basalt]

ye

[onyx violet]

im having issues with action mappings and axis mappings being different in packaged builds

is there anyway I can make sure that the action/axis mappings in the editor are synced with packaged shipping builds

[white elbow]

why do FBX files I import are always giant, and .obj files are always small?

[earnest tangle]

format differences, export/import differences, etc.

at least in blender you can configure the scale and such for your scene and for exporting, so you can get the scale to match in both it and UE

[timid thunder]

Would anyone know how to make a character rotate at the mouse position smoothly?

[trim matrix]

Hi everyone! i have an object with 200 tiny LED lights geo on it, and i need to animate each lights with differents colors, and intensity... do you know how to do so? would it be better to do it in BP or in the material?

[timid thunder]

Probz in bp but you will have to make a timeline for the alpha

[solemn bramble]

There is this function: https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Game/Player/GetHitResultUnderCursorbyChannel/

[solemn bramble]

You can use it to get the location to which you should rotate your character, I do it by simple SetActorRotation. If you want to do it smoothly, you can use for example Lerp.

[odd ember]

for 200 lights material would be cheaper

managing 200 lights in BP will be very expensive

and you'll have to consider performance

in materials the LEDs could just be emissive

[cosmic charm]

Is there any way to add another widget here by pressing a button inside the first widget. Or can i only just create a widget into the viewport or change visibility

[thin panther]

You xan use add child instead of add to vieeport

But why do you have 2 nested canvas panels

[cosmic charm]

don ask

[timid thunder]

would I use find look at rotation?

[solemn bramble]

You can, just ignore Z

[timid thunder]

would i also use add or set? (sorry ive never used this function before)

rotation

[trim matrix]

ok will do!

[crude pecan]

Is there a way in blueprints to force Fullscreen (F11) when Play in selected viewport is clicked in the editor? I'm not talking about standalone game

Found a solution, use the command LevelEditor.ToggleImmersive

[odd ember]

glad we could help 👍

[thin panther]

But i am asking cause its bad

[odd ember]

woah man that's #toxic

[cosmic charm]

whats toxic about it

[thin panther]

Oh no ;-; my life is ruined

[thin panther]

Just a lil joke

[crude pecan]

Is there a way to detect PIE exit? I want to trigger an event when ESC is pressed...

[odd ember]

in CPP most likely, but you'd have to expose that to BP. generally intra editor operations are handled through cpp exclusively

[crude pecan]

Yeah I just wanted a slight modification to the solution I have above. Remembering whether they were in immersive (F11 fulscreen) or not and on exiting pie reapply whichever mode they were in

[odd ember]

right but that does not change anything

you'll still have to go through cpp for stuff like this

tbh the entire thing sounds like something worth considering an editor subsystem for

[crude pecan]

NP, just wanted to be sure. I've seen there are ways by rebinding exit to something else, but that's not something I want to do

It's just for an editor tool

and it's handy that it fullscreens when PIE is hit for UI stuff

[odd ember]

I've never seen anything like this before in BP. in fact I wouldn't even know which class would access this that would be exposed to BP from the get go. generally editor functionality through BP is severely limited, and I've hit roadblocks myself when making tools

[crude pecan]

This vid might help. Here I haven't got the UI up yet, but you can imagine that there are some controls there for variables. Excuse the Soundgarden 😅

I'm not in fullscreen here but would imagine the ideal use case would have fullscreen enabled

[odd ember]

like I said, I don't think you'll find a solution outside of cpp

this is different than the console command hack

because you need the delegate that triggers when PIE stops

which is probably deep inside the engine

[crude pecan]

No problem, it's not the end of the world

Thanks for the insight though

I think they can live with having to press F11 on exit, or I'll just make the UI a little more tolerant to weird aspects

Never mind I solved it

😅

end play event

[odd ember]

just remember that that will trigger regardless of PIE

[crude pecan]

As long as it's only in this blueprint which is only used for this tool that should be ok?

This tool is only for editor side and would never end up in a packaged game etc

it generates content for the content browser

[odd ember]

right but right now it's going to get packaged. you can see if there is a tickbox for the BP event to make it "editor only"

[crude pecan]

looks like you can set it based on whether end PIE was the reason

[odd ember]

good find

[crude pecan]

Also this just lives in a level BP for the level for this tool

so if someone puts this in their game.. thats on them 😄

But thanks for the sounding board 👍 onward 🔥

[tulip mural]

Hello, is there a way to make an actor interactable only once ? Currently struggling with this, would like to make only one actor activated at a time while making a loop with the three other ones

[odd ember]

you can use a DoOnce or use a branch with a bool that is true the first time, but then gets set to false afterwards

[tulip mural]

oo thanks 🙏

[steady night]

hey guys, how do i turn on so i can se my flow when im testing the game ?

like thee BPs i can se the actual flow when doing stuff

[hexed glade]

On the top of the editor in the blueprint you want to view the flow of you can select the instance you want to view the flow of in the debug filter(character, controller, etc.).

[steady night]

@hexed glade"Simulations" ?

[solemn bramble]

Definitely Set

[hexed glade]

First you open up the blueprint you want to watch. On the top right, next to play there should be a debug filter.

[steady night]

yeah

but is only says "no debug onjects selected"

[hexed glade]

What type of blueprint are you trying to view?

[steady night]

well any really

says it on all

[hexed glade]

In general. You have to have an instance available in the level for the blueprint when you want to view the flow. So if it is a character, then you need that placed in the level. If it is a controller you need to have it attached to something that is active when you hit play. If it is something that spawns in, I think you can select it later after you've hit play.

[steady night]

ah i se

oh i had to press play before selecting the degbug

gotcha 😛

also you know ov any help - sections on discord for newbies ?

cant find any

[odd ember]

🤔

[hexed glade]

I've mostly used the blueprint section and some others that fit the theme of my questions. Pretty new here myself 🙂 People here are pretty friendly so just ask around and they'll probably guide you in the right direction.

[steady night]

alrighty

ty

[hexed glade]

Got a question here I hope someone can answer. How do you use timers for a function that will activate multiple times before the timer finishes without having the timer refresh (aka, separate timers)? I've tried using delays, but that doesn't seem to work.

[odd ember]

can you rephrase that in a non technical way? what is it you want to have happen?

[hexed glade]

I have an ability cooldown system. I'm trying to after having set the ability on cooldown, make it available again after a certain time. I have multiple abilities that can be on cooldown simultaniously.

[odd ember]

each ability has to have its own cooldown timer

[hexed glade]

Yes, and I forgot to mention that the abilities are contained in a structure as there is only 1 ability slot.

[odd ember]

so if you have each ability on its own cooldown timer... you should be fine?

[hexed glade]

I'm just having a bit of trouble finding out how to set up multiple timers from a event (ability activation). Any tips?

[odd ember]

okay that makes it sound like you have a different issue?

because setting up multiple timers shouldn't be an issue

it's just putting them onto the same execution thread

[gentle urchin]

Only 1 ability slot but multiple abilities with different timers? Huh?

Just do a timestamp

When used

You can work out the rest based on time delta and cooldown time

[odd ember]

yeah I'll wait for a better explanation

my current take is that you have an architecture that isn't setup properly atm

[gentle urchin]

Yeah thats what i got from it aswell really

Then again im clearly missing a lot of context &&

[hexed glade]

Yeah I think I can get it working by using timestamps. Thanks for the advice. In case the explanation helps. I have a single ability slot that you can swap inn and out abilities that, when used goes on cooldown. So when the ability is swapped out it goes back in the array containing all abilities. I have gotten everything to work about the system, just need to fix getting the ability off cooldown.

[odd ember]

you should really setup the system first

before trying to do individual things with abilities

[azure night]

Whats the most elegant way to enter a transition based on an enum? E.g. if the character is jumping, this transition should be true and happen

[odd ember]

code architecture has done be done top down

[gentle urchin]

[odd ember]

if you search in this channel I gave some advice on how to setup animBPs correctly to @onyx token

Stupid april fools, i can't trust this server now

thank you alot, i'll look for it!

hey guys i have a issue ive been tring to solve for ages its quite complicated to explain and (help with i suppose) im following a tutorial doing a inventory / equipmentsystem but ive got some bugg that i cant find the solution for.... look at gif and if u got time to help let me know

https://gyazo.com/62f1d10db043b0956dc34836fa79a4e9

the weapons work as intended as based on same parent bp
the "breastplate works as intended from the same parent bp as the (shield & helmet) but they dont work and when im equipping the breastplate well you se what happens

[mossy perch]

Need some help
Trying to perform an off-axis fulcrum shift to prevent pop out of objects within a scene which have a positive parallax
But can't figure out a way to get a change on the matrix values, at all -.-

[fair magnet]

what's this thing and how do I make it go away <-<

[gentle socket]

How will something like this compile - will you get the new last index or go out of bounds getting the index you just removed?

[fair magnet]

since you're removing last you're getting new last yes

[gentle socket]

that's confusing, then the two lines from the "last index" node would return different values

[torpid hound]

They will return different values because it's begin called at different times

[lethal surge]

That’s for debugging but as AnimBP are always evaluating it shows up in editing. There is a flag in editor settings to turn if off.

[fair magnet]

I'm not even inside the anim bp :o

Or... have one at all

[lethal surge]

Where is it? What BP class?

[fair magnet]

that's inside a gameplay ability class

but I had it in pawns

playerstates

basically everywhere

[lethal surge]

And it’s during editing or during debugging?

[fair magnet]

during editing blueprints

seems to occur at random

[lethal surge]

That’s weird. As said you can turn it off in settings.

[fair magnet]

do you roughly know what it's called?

[hexed glade]

Found out a solution to my ability cooldown trouble and thought I'd share.
I used a basic actor to track the cooldown with a On Destruction effect tied to the event cooldown effect. Thanks for pointing me in the right direction guys 🙂

[azure night]

[Question] Do enums not automatically get updated across blueprints? I've got my animation blueprint transitions hooked up to enum states, the animations work in the preview window, in game, the enum states are being changed, as I print them to the screen, but the animations do not work?

[fair magnet]

[Answer] Depends on how you have set it up

[lethal surge]

I think it's the Enable Pin Value Inspection Tooltips setting in Editor Preferences

[azure night]

Ive got got the enum as a variable inside the animation blueprint. I've done the same on my movement script, and that lets me update the enum, but those changes dont seem to trigger inside the animation blueprint

[fair magnet]

Are you sure it's setting this exact variable?

[azure night]

First image is inside my player blueprint, second is inside animation blueprint

How do I get the instance of the enum after the event update animation?

Sorry im not sure how to implement that, can you explain how? How do you get the enum value from the other blueprint within the animation blupeprint

[fair magnet]

theres probably some node that's called Owning Character or smth like that... idk... never using animations

get that-> cast to whatever class your character is -> get the enum

set it

#animation

[bright harbor]

so i have a rail grind system, and i know how to make it go backwards, but i need help, how would i make it so it automatically decides if the player should move forward or backwards along the spline?

[fair magnet]

not sure how your system works but...
Maybe at your "attachment" logic you can check the direction the character is facing

[gentle socket]

Is it possible to have a local variable work as a reference to a list?

so you'd set a local variable to the list of another class

[fair magnet]

Further explanation required

[gentle socket]

On it, one sec

[bright harbor]

i have it to where the player sets its location along the spline on tick, based on a speed float, and to reverse it i multiply by -1, but i don't know how to make it so the player direction changes the direction variable

[fair magnet]

I'm very unexperienced with splines... what you could try is messing around with the "Find closest x to world location"

might work if you somehow can determine the velocity direction relative to your spline

[gentle socket]

I have an object blueprint which has a list of the same object. The idea was to use this object like a node in a tree structure, so each node contains a list of further nodes. I'm now trying to create the tree structure and traverse it without using recursion.

For this I have set up a second class which holds the root node object. Then in this object I would like to have a variable to which I can assign these sublists. For traversal, I would assign to this local variable the list of subnodes that the root node contains, so that after that I could add subnodes to this list.

Then in turn I could assign one of these subnodes to the local variable and alter that list, and so on and so forth

but I'm not sure that's possible

[fair magnet]

I'm very unsure what you mean by "list"

[gentle socket]

Currently I'm using a map:

[fair magnet]

like an array?

[gentle socket]

yeah

Then for traversal I'd need a local "reference" map like this:

and then I'd assign to this local reference the map from the object

[fair magnet]

Literally don't understand o.o
So you Have this map right there...
And you want this map to store multiple references of itself?

[gentle socket]

:s

The NestedBinds on the KeyBind object is a map that contains more KeyBind objects

[fair magnet]

yea sure

[gentle socket]

Then I have a second KeybindManager class which contains one KeyBind object, the Root Keybind

[fair magnet]

but why?

[gentle socket]

So that I can create a tree structure with these Objects

[fair magnet]

Why do you need to nest it so much?

Can't you just create a "key" value like the buttons you're binding
attached with your keybind object?

[gentle socket]

I'm making some program which contains a fairly large number of keybinds which contain multiple keys

and there's lots of keypresses a second

[fair magnet]

So you want to be able to assign multiple keys to one action?

[gentle socket]

For context these are MIDI keys

[fair magnet]

if so just make it a structure give it a name, and array of Keybindings then make this structure an array instead

[gentle socket]

The thing is if you use an array with combinations

you'd have to check against all combinations with each press

[fair magnet]

not necessarily

if you know which index it is

you can just get it

[gentle socket]

So you basically index with a combination of keys?

[river herald]

In player controller i overrided the onpossess function, is there a way to reset to default?

[fair magnet]

delete it

[river herald]

I did and it still isn't back to normal

[fair magnet]

well... i do not know what your intent is. So...
What you can do is since it's midi keys you probably get some kind of midi value returned if you press a button right?

[gentle socket]

yeah

[fair magnet]

like... idk.. the key that got pressed

is a number

[gentle socket]

Yes it's an integer

[fair magnet]

do you know is the very first key

0 or 1 ?

[gentle socket]

1-88 for keys

[fair magnet]

no 0 ?

[gentle socket]

probably reserved for something else

[fair magnet]

then you just create like 88 array entries and you're done

or 89 I think

or you

[gentle socket]

That would work if it weren't key combinations

[fair magnet]

subtract by 1

[fair magnet]

so you press like for example 1 and 5 and stuff happens?

[gentle socket]

so I'd somehow have to combine these into an index. You can technically do that with a map

yeah

[river herald]

I overrided the onpossess function in player controller and now my pawn isn't spawning, its just possessing a camera. I don't know how to undo

[fair magnet]

I don't know if midi works with enhanced input but you should absolutely try using that

[ancient siren]

im trying to make it stop animating when i stop punching, because when i stop it continues the last frame of the animation until i do something else. if you need any more code or a video to show the issue that is completely fine- heres the bp (im new ish btw)

[fair magnet]

it let's you define modifiers and trigger conditions for certain input events

[gentle socket]

Those are just events then?

[fair magnet]

yea

and you can do multiple keys which fire multiple input events

(if they don't consume input)

then you can bind this action to one or more keys

[fair magnet]

#animation

[ancient siren]

k

[gentle socket]

I think I don't even need that then. The MIDI plugin as is generates events for all sorts of stuff. Like key down, key up, the value of a slider, and so on. Along with a control ID (for the specific key/slider), and a value (how far up, how fast it's been pressed).

I think I can simply keep track of a set of currently held control IDs. Then do something funky like combine these into a string, and use that to index a map of keybinds

which will then be a flat map, not a tree

sounds good

[fair magnet]

I just assumed it was exactly what you needed :o As I said I do not know if that works with midi as it replaces your input actions

[river herald]

does no one know how to undo an overridden function?

[fair magnet]

you delete it

and if it still doesn't work it's something else

Something we do not know about tho

[river herald]

When I overid it (onpossess in player controller), it appeared as a event in bp, I deleted that and now at begin play my characters are just cameras

[fair magnet]

[gentle socket]

Might be one thing left to figure out though. The main reason why I wanted to do a tree first is because in practice you use it as such. e.g. you press one main key, then it displays nested keybinds and you press a follow-up key. With a tree this is easy since you can just get the follow-up keybinds from the list the first key stored. But with a flat list you can't do that as easily (since it's not easy to find the binds which require one more key)

[fair magnet]

have you tried restarting?

[gentle socket]

Can probably get away with storing a separate list with keybinds required to display it. Which would be all the keys up to that point in what would have been the tree. This is breaking my brain :)) Thanks for thinking along

I need a thinking break

[timid thunder]

You will have to add the animations to your anim blueprint and make a new var call is attacking and then play the animation you want and the conditions is when your attacking

[timid thunder]

https://youtu.be/1jxElVA7g3c

[ancient siren]

bruh I just left home ok

ty

I'll look into it later

[timid thunder]

Also your question is for #animation

[ancient siren]

I sent it in there

[trim matrix]

Hi everyone! do you know how set relative position and make sure object won't overlap?

right now i'm spawning 200 spheres using random unit vector, but many of them overlap each other, and i would need to avoid that...

(avoid collision)

[fair magnet]

ohhh now I know what you're after :o
WELL
Since you have a "Keybind"-Object (I don't even know how you're constructing them)
but basically you'd go like this:

(Note that you still need to create child classes to change specific values)

[gentle socket]

This looks very promising

similar to what I had already made myself, I'll have to compare it to see what I have to change

[fair magnet]

Well I don't know if it works XD it's just a theory

[gentle socket]

Where did you find this?

[river herald]

my game's broken by clicking one button

[fair magnet]

I made it?

[gentle socket]

I see

[river herald]

when I click play the games not spawning a character for my player controller to possess, im just a camera, how do i fix this

[fair magnet]

try this... if it overlapps it retries with a random vector further a way if you need it to be more far away each try try increasing the 10 to something like 25

Or even more if you need it

Oh I forgot the most important part lol

there u go

[river herald]

what's the difference between the target being actor and controller. How do i access the default onpossess function

[fair magnet]

One would think it's the target

[honest wolf]

Hello there. I'm encountering a weird bug and hope someone has experienced this before and can help me resolve this.

No matter what I do, I can't get the Input node to ever get to delete pins / variables, adding seems to work fine. In this example I deleted all Inputs were deleted, the Input node still shows them though.

I tried refreshing nodes, the blueprint, all blueprints, 4.26, 4.27 and 5.00 P2. I can still connect the non-existing nodes and compile just fine. It will obviously crash though when hitting play.

[fair magnet]

I assume you already did restart?

[honest wolf]

Yeah.

[fair magnet]

what if you copy n paste the function?

[honest wolf]

You can't paste an input node.

[fair magnet]

yea but the entire function

[honest wolf]

Ah, I see. Yeah, that seems to work. Thanks for the tip!

Odd

[trim matrix]

Hi Ayes! awesome! trying right now!

[river herald]

Where do i find the function for spawning default pawn on begin play?

[trim matrix]

how do you get that node?

[odd ember]

right click on pin > split

[trim matrix]

alright done. my issue is i can't connect the list of objects to the "get world location"

mine are static mesh component

[fair magnet]

how did u do it there?

[trim matrix]

simply like this

[fair magnet]

yea but what's the target pin? like show what's it connected to

[trim matrix]

to the output "array element"

*from

[fair magnet]

then connect that

o.o

[trim matrix]

i tried

but it says static mesh component object reference not compatible

Hi all, my flappy bird clone is almost complete... one last thing I want to add is the rotation on the bird when the player taps (rotates upwards to 20 Y axis), and the rotation downwards when the player isn't tapping (rotates downward -90 Y axis).

I'm trying to work out the best way to do this... I've tried a LERP but it didn't really work (maybe I am using it wrong), it never seemed to get to the full 20 degrees unless I was spamming the button really fast.

I've also tried without a LERP and just setting some arbitrary values, adding these to a temporary rotation (float) variable, multiplying by delta time and then setting the rotation. This seemed to get me closer to the result I wanted but I couldn't seem to get both the upward and downward rotation to work as expected with this approach.

Any thoughts on a suitable approach? Perhaps something I've not thought of that would be more straight forward?

Trying

[hushed pewter]

The print string is giving me the right segments of string, but after its converted into text var the first two "Sets" are blank. But only the 2nd time

Even when the print is connected to the to text it works

[mellow folio]

I assume you’re running the rotation lerp only once, believing this works over time

But it doesn’t

[keen wedge]

Its in Event Tick... so being called multiple times, I'm applying the delta time to the alpha, and also multiplying that by the velocity of the bird.#

[mellow folio]

Why multiplying by velocity

Also, make sure shortest route is on

[faint pasture]

If you have vertical velocity, remap it to the angles you want and you're golden.

[keen wedge]

I've seen a node for that, but its name escapes me...

MapRangedClamped

?

[faint pasture]

Yes

Map what z velocity you want to corrosponds to what angle and hit it on tick

So it doesn't respond to the tap, it responds to the actual velocity, which gets a bump whenever you tap

[keen wedge]

hmmm, ok... bit confused as to what I plug into where... there's two "ins" and two "outs" etc... presumably one of the ins would be its currently rotation.... and the two outs would be the "20" and "-90" degrees?

[mellow folio]

Post pics

[keen wedge]

I can, but its a bit of a shit show at the moment as I've been trying different things and its a mess... will see if I can declutter it a bit...

[faint pasture]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Math/Float/MapRangeClamped/

That's all you need. Plug velocity Z into the input and select what velocities you want to map to what angles and then set the pitch

[keen wedge]

The velocities would effectively be anything "above" 0 and anything "below" zero...

There's not really a "range" for that

?

[faint pasture]

Call it 1 and -1 then

But it'll look a lot better if it's like 100 and -100 so it doesn't snap and smoothly rotates at the peak of the trajectory but you do what you want

Try these inputs.
Velocity.Z
100
-100
30
-30

Then tune to taste

[keen wedge]

ok... and then the output goes to the Y for the rotation I guess?

[faint pasture]

It goes into whichever rotation you want the thing to rotate around, I don't know if you're pitching, or rolling. Just plug it into something and see what happens. I'll take you two seconds

[keen wedge]

will try now

[faint pasture]

This is just a function that transforms velocity into an angle. You pick what velocity corresponds to what angle and then plug it into a make rotator and set the rotation

It's basically a remappable linear transformation. Very useful all over the place in games

[keen wedge]

So which of those values you suggested are the angles?

I can't quite see how it gets the "20" and the "-90" from this?

(yet seems to be almost spot on, albeit a little snappy)

[faint pasture]

The first input is the actual input value you're reading, the second and third are the min and Max for that that you want to consider, and the fourth and 5th are what outputs you want to map to those.

So what the numbers I gave you, an input of 100 would result in an output of 30

And an input of -100 would result in an output of negative 30, and in between, it would interpolate

If it's too snappy, make the input range bigger.

[keen wedge]

turns out I was still running half of my previous code for the "fall"... so this was only being applied for the "flap"... will cut out my other code a sec...

[faint pasture]

But if your velocity is instantly changing, your angle will also instantly change. If you want it to lag behind you will have to do an interp to.

[keen wedge]

Sorry @faint pasture, I'm getting quite lost quite fast at the moment...

[faint pasture]

Get this remap range working and then if you want it to lag, you can use the output of this remap range as Target angle, and then interpolate towards Target angle with a finterpto

This should be the only thing touching your bird rotation.

[keen wedge]

Yeah, it is... but it doesn't end up -90 degrees vertically etc... changed the second out to -90 to see what would happen, gives me the vertical fall, but the bird now starts off pointing towards the floor a bit...

(when it has zero velocity)

(main menu screen)

[faint pasture]

Yeah so think about it. You want zero to map to zero, so if you have uneven outputs, you want an uneven input range as well.

[hollow gorge]

How can I delete variables from the output node of a custom function? I can add variables but don't see an "x" or remove option

ah solved it, I have to delete the return node and just add a new one

[keen wedge]

Im feeling really kinda stupid because this isn't making any sense to me...

I get that if I had a range of 1-10, this could map that to 10-100 for example... but my velocities are not constant (so to speak), the only thing I know is the angles I need.

it is close though...

[faint pasture]

Make the third input a little lower.

Making it take a higher downward velocity to reach negative 90°

[keen wedge]

Slowly getting closer, but it does nose dive a little too fast...

these however are much better...

out of interest... at the moment I'm only plugging in the birds velocity, this is being run in Tick... do I not need to plug in the delta time at all?

[scenic kindle]

any reason why this cast is failing?

but this one isn't?

[grand valve]

Because the save is a playsavegame object not a customizationsavegame

[scenic kindle]

so i have to save them to two different slots?

[grand valve]

If they are two different objects yea

You can combine the classes if you want

Wherever you are creating and saving your save game, you see creating one of a certain class, in this case it seems to be playsavegame

[scenic kindle]

yes, before I switch levels, i overwrite "Save" with playsavegame

[grand valve]

Yea so by definition, the saved slot at "save" becomes a playsavegame, therefore cant be the other one

[scenic kindle]

so should I save the other one to a different slot, or just move the variables over to playsavegame?

[grand valve]

Its up to you, at that points its just a organizational thing, but you'll need to do one of those

Easiest is to save the other one to a different slot

[scenic kindle]

ok thanks. i didn't know save game slots were object-oriented

[grand valve]

Yea, there a little different because you load them from a string path, and then need to cast them to their proper class, so you do need to keep track of what class you're saving with what name.

[scenic kindle]

because it's a string, the fact that it's case sensitive gets annoying at times

[keen wedge]

when I did something similar I created a couple of structs.... one for the player data, and one for the game data.... wrapped them both in a further struct and then saved that

[grand valve]

Hmm, is it here? I didnt know that..

[scenic kindle]

that might help

[keen wedge]

from memory, it was something like this:

BP_SaveData (inherits SaveGame)

• PlayerData (structure)
• GameData (structure)

each of those structures you can then add your own properties too as necessary etc

[faint pasture]

Nope.

You'd need delta time if you were doing some time dependent thing like an finterpto

This is just a simple function. You could just as easily do angle = velocity/3 or whatever

[grand valve]

You can also promote the save name to variable that way you'll never have a mismatch between load from slot and save to slot as long as the variable is plugged in

[keen wedge]

Its much better, so thank you for getting me this far @faint pasture , the only minor niggle I have now is that, when I output the velocity the maximum value I see is 314... so it would make sense to set that as the first input, so it correspond with the 20 degrees...

[faint pasture]

If that's what you want then go for it

[keen wedge]

but working it then backwards, from the -90, would give me a velocity of -1413, which I never reach...

so, I either have not quite reaching 20 degrees up, or, not quite reaching -90 degrees down...

[faint pasture]

It clamps.

[keen wedge]

(in order to keep the inputs balanced so that they can zero out)

Oh, so the "actual" velocities dont matter so much?

[faint pasture]

I mean if you give an input outside of the range, it'll clamp to the range.

[keen wedge]

ok, so in that case I'd be better of working out the negative velocity for the -90 I think... plug those in more accurately, then use whatever the ratio is between those to establish the value for the 20 degrees... (I think)

[faint pasture]

Ok give numbers. You want what velocity to map to +20 and what velocity to map to -90?

[keen wedge]

I apply an impulse (calculated based on the gravity and enough force to get a specific height) of 331.299988... BUT... when I output the velocity, the max value I'm seeing is 314... I suspect this is because gravity has already been applied for that first tick?

Assuming so... 314 would be for the 20 degrees "up"

[faint pasture]

Yeah gravity is doing that

[keen wedge]

max downward velocity is a bit trickier to tell, as the higher put the screen the player is, the more it will be... in the original game however, it will often already reach -90 degrees before it gets to the floor, so guessing the value is capped in some way..

[faint pasture]

Try this

[keen wedge]

(doubling the values seemed seemed to keep that zero point that was needed etc)

[faint pasture]

Try 100 ->20 and -450 -> -90

[keen wedge]

I would say thats pretty much perfect!

multiples of 5 on that one yeah?

[faint pasture]

So what it's doing there since this is map range clamped, is there anything above 100 still maps to 20

Anything below -450 maps to 90, and I pick those numbers so zero maps to zero so it's horizontal at the peak

[keen wedge]

big hugs 🙂

thank you sooo much for taking the time to help me out with this (not the first time you've helped me I know)...

[hollow gorge]

Hello, is there a way to make the "slots panel" grow elements / push elements to the opposite side?

it's currently growing [new] -> [old] I'd like it to be [old] <- [new] instead

[odd ember]

is this a #umg question?

[trim matrix]

Why does my trace go thought the character even though ive set it to respond to hit events on camera and visible?

[odd ember]

both collisions need to have the same value. so whatever your trace is, it needs to be blocked by the mesh

[trim matrix]

ah ok

[half tulip]

How can I learn what fancy blueprint words like "Transform" mean and what it's used for?

Roughly how many months does it take to learn all the Math API References? I'm also not very good at math but want to learn how to use blueprints

I feel overwelmed by how many Blueprint API reference there is will it take forever to learn all the available nodes?

[odd ember]

all "fancy" blueprint words have their root in programming and math terms. a transform exists the same way outside of blueprint as it does inside

how long it takes to learn it is depending on your own ability

[half tulip]

I should of stayed at school longer to learn the math terms 🤦‍♂️

[odd ember]

there's also a distinction in how well you can use blueprints. almost anyone can come in and do basic prototype work

but if you want to do something more substantial, and have something that needs to be more polished for a game release, you'll need a more thorough understanding of programming

math in a general sense is just a small part of what blueprints are. most of the time you're dealing with discrete logic

[half tulip]

I just want to become proficient enough in blueprints that I can intergrate marketplace assets together and also create my own logic

I will pay $1000 to accomplish this proficiency

[odd ember]

that's a very broad statement. marketplace assets don't come in just one variety, and you'll find that some are much more polished than others

[half tulip]

I want to be able to call myself a developer and not just a designer

[half tulip]

Without knowledge of blueprints it's quite difficult sometimes to intergrate various marketplace assets together without help

[odd ember]

a "developer" won't just stick with blueprints, they'll delve deeper inside the cpp code that constitute blueprints

and equally, a developer will have to have a more thorough understanding of system architecture at a high level, and core optimizations at a low level

[half tulip]

I feel like being profecient in blueprints is enough to earn yourself the "developer" title as it is still a form of programming.

Some developers are just more advanced than others

[odd ember]

you can call yourself what you want. but will people hire you as a developer? unlikely

[half tulip]

I think you are underplaying the doors that being proficient in blueprints opens

you can make a whole game in blueprints without touching CPP

[odd ember]

I don't personally know of any studios that hire people as developers for blueprint only work, and I work in the industry

[half tulip]

I'm not really interested in working in the industry. I am going the indie route

[odd ember]

well then call yourself whatever you want

at the end of the day your title matters less than the work you are able to put forward

[half tulip]

not really... i don't like to give myself a Title that i haven't earned, it's distasteful. Indie's have standards too

[odd ember]

well that's your prerogative. do what you like.

if you're not worried about getting hired anywhere there's nothing to hold you back

[half tulip]

I have respect for my fellow Indies who have learned blueprints and have become profecient in it, so I won't call myself a dev until I am profecient enough in blueprint that i don't have to rely on outside assistance for putting my games logic together

[faint pasture]

Don't touch marketplace assets until you kinda know your way around. Start with one of the template projects and add some stuff. Simple stuff. Simpler than you're thinking. Even simpler than that.

[faint pasture]

You're not here to learn Blueprints, you wanna learn programming in general. Someone who knows general programming can make something in BP on day one.

[thin panther]

and youll always likely need outside assistance

you never stop googling things

[faint pasture]

True.

[odd ember]

unless you put together your own pc, create your own internet etc.

start by mining your own ore

[thin panther]

i mean thats the only logical route nowadays

[half tulip]

Not unless they know CPP specifically

[thin panther]

government cant track me if i make my own

[thin panther]

but they can

[odd ember]

hope you're good with circuits

[half tulip]

nope
